Pipe(|) separated custom annotators not recognised

1. tried with kapt ->
Malformed string 'x.y.z.DeepLink|x.y.z.PublicDeepLink' for a supported annotation type returned by processor 'org.jetbrains.kotlin.kapt3.base.ProcessorWrapper'error: Error creating fileNote: No deep link, DeepLink doc not generated.

2. tried with ksp, module registry didn't auto generate

No files or tests are named. Start by reproducing the pipe-separated custom annotator case with kapt and the missing module-registry generation with ksp; done means both processing paths recognize the annotators and generate the deep-link documentation or module registry.
